No, the GP and 686 are equivalent. The N-frame being considerably larger than both. The Security Six is more comparable to a K-frame.Sorry for the quibble, but the 627 is the full sized (N frame) .327, more comparable to a GP100. My 686 is more like a Security Six, which is so popular it seems like it should be reintroduced by Ruger. There is a real gap between Rugers SP101 and the GP100, which my S&W 686 fills nicely.
The Security Six was dropped because it was too expensive to produce at the price point they wanted. It won't be coming back.
